abstract = {Introduction: Complex Training (CT) has been used to achieve Post-activation Potentiation (PAP) of physical
capabilities and, in doing so, improve the sports performance of athletes. However, few studies have
considered alterations in serum Cortisol, Metabolic Creatine Kinase (MB-CK), Total Creatine Kinase (Total-CK),
and Lactate concentrations ([La]) resulting from this training method. Objective: This study determined the
behavior of the following blood serum substances in a CT session: Cortisol, MB-CK, Total CK and [La]. Method:
Ten military athlete volunteers aged 28.5 ± 4.8 years; 66.2 ± 2.8 kg, 171.4 ± 3.7 cm, 22.6 ± 1.2 kg/m2; 11.3 ±
2.9% of fat tissue took part in the study. The study had a quasi-experimental, intrasubject design. The variable
measurements were: Cortisol, MB-CK, Total-CK, and [La], measured before physical exercise and 24 hours
post-stress. The CT session consisted of: four series of five repetitions at 30% of 1RM, plus four repetitions at
60% of 1RM, plus three throws of a 575 g projectile, 15 seconds apart. The statistical analysis was carried out
through repeated measure ANOVA for Lactate and a Wilcoxon Matched Pairs t-Test for Cortisol, MB-CK and
Total-CK. Results: There was no evidence of alterations in the indicators for fatigue ([La] p = 0.36), and muscular
injury (Cortisol p = 0.16; MB-CK p = 0.23; Total-CK p = 0.64) after the training sessions. Conclusion: Variables
for muscular injury showed no evidence of alterations 24 hours after the CT sessions, hence confirming that
the workload did not generate significant post-stress muscular injury. Level of Evidence I; Therapeutic Study:
